Application filed February 21, 19119. wrial Ho. M5341.

To all whom it may concern:

Be it known that I, Pnrnn VIGGEN, a citizen of the United States, residing at Chicago, 111 the county of Cook and State of '5 lllinoishave invented certain new and useful improvements in Magazine-Slots for Coin- @perated Musical Instruments, of which the following is a specification.

This invention relates to improvements in a mechanism tooc used in connection with that class of musical instruments in which the pneumatics thereof are operated by ineai'is of electricity for making and breaking contacts offer-starting and stopping showing the motor which operates-the instrument, and it consists in certain peculiarities of the construction, novel arrangement, and operation oi" the various parts thereof, as will be hereinafter more fully set forth and spe-.

cilicelly claimed.

'lhe principal object of the invention is to prov de a, mechanism of the ahove nanied character to be operated by the deposit of: one or more coins and is especially intended to receive several coins one at a time so that a number-of tunes or pieces of music may he played by the instruinentone after the othler'without the necessity of depositing a coin at the end of each piece ortune.

- @ther' objects and advantages of the intention will be disclosed in the subjoined de cription and explanation.

In order to enable others skilled in the art to which my invention pertains, to make l? and um the same, 1 will now proceed to deseriho it, referring to the accompanying drawing, in which 4 Figure l, is a view partly in section and partly in elevation of a magazine slot mechanism ,e wodying the invention, showing the parts in their initial positions or out of contuctdsfhey will appear when the musical instrument is at rest, or not in operation; Fig. 2, is a similar View of like parts, but them in contact or in position for playing a number of tunes or ieces; and Fig. 3, is a fragmental perspective view of a portion of the ratchet-toothed rack and a portion of the contact. plate which it carries.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawing.

The reference numeral 5, designates the main or supporting-frame of the mechanism, which mayshe made of any suitable size, form and material, and adapted to be secured in the musical instrument at any suitable point. The frame is provided in one of its sides with a coin chute 6, for conducting the deposited coins to a suitable recep tacle therefor, not shown. The upper por- Ation of the casing orframe 5, is provided iv-with a slot 7, which may have communica- Etion with a coin-conductingchute (not 1 shown)" leading from a suitable point in the casing of the instrument, for admitting coins to the chute 6, for actuating the operatinglever. The rear portion of the casing or frame 5, is provided near one of its sides with a vertical groove 8, or guide way for the rack 9, which has on each of its sides a series of ratchet-teeth 1t), and 11, for engagement' with spring-actuated pawls used c'or raising and lowering said rack. The rack 9, is made of fiber or other suitable insulating material, and has on its rear portion a vertical cleat 12, to fit in the guide way 8, and on its front surface a metal-plate 13, which is extended to near the ends of the rack. Fulcrumed at one of its ends on the frame 5, is an operating lever 14:, which is extended through an opening 15, in the upper portion of a partition 16, which divides the coin chute 8, from the mainportion of the casing of -frame.

was

As is clearly shown in Figs. 1, and2, of

u H pro ection 12, of said rack, thus assisting in holding the reel: in position. Extended inwardly from the back of the casing or frame 5, are two stop pinsor projections 17, and

18, located above and below the operating lever 14;, and used for limiting its upward and downward movement-s. Plvotally secured at one of its ends to the operating lever 14, near the rack 9, is a depending pawl 19, adapted to engage the ratchet-teeth 11, on one. side of the rack This pawl is actuated by a spring 20, which has one of its ends secured to the upper portion of the pawl and its other end to a screw or projection 21, on.

the operating lever. Located in the lower portion of the casing 5, is a pneumatic of the ordinary, or any 'well known construction which has on its lower portidn atits free end an extension ore-r0122, ,tovfhich is pivotally secured. .near its free end lower iii n alrrl pawl 23, which has its upper portionprovided with two bends 24, and 25, to coact with a pin 26, secured to the back of the casing or frame in such a manner as to hold the upper end of said pawl out of engagement with the ratchet-teeth 10, of the rack when the pneumatic 27, is inflated but to permit it to engage said teeth when said pneumatic is deflated. The pawl 23, is pressed toward the rack 9, by means of a spring 28, which is secured at one of its ends to the pawl and at its other end to the oxtension 22, which extension also has pivotally secured thereto the lower end of a rod 29, which is pivoted at its upper end to one end of a link 30, the other end of which is pivotally secured on the back of the frame or casing and in such a manner that said link shall extend across the rack. The upper portion of the pneumatic hasleading therefrom a tube 31, which communicates with a primary or power pneumatic (not shown) of the musical instrument. Qecured to the hack of the casing or frame and insulated there from by means of blocks 32, of suitable insulating material, are a pair of contact springs 33, and 34:, each of which has its free end extended into the path of the metal plate 13, which is carried by the rack, against which plate and rack the sprin s 33 and 34:,

will contact so as to frictiona ly hold the rack in position on the frame. Connected to the contact springs 33, and 34, by'means of binding posts 35, are electric conductors F 36, and 37, which lead to the motor (not shown} used for operating the neumatics of the instrument. The operating lever 14, is normally held with its free end in an elevated position as shown by continuous lines by means of a spring 38, which has one of its ends applied to one side of the frame 5, and is passed over the fulcrum .39, and has its other end in engagement with the saidever.

From the foregoing and by referencc to the drawing, it will be seen and understood that when the parts are in the positions shown in Fig. 1, the contact spring 34, will be out of contact with the metal plate 13, and that the pneumatic 27, will be inflated and the extension 22, thereon, held in its lowered position by means of the spring 40, which is connected at one of its ends to the partition 16, and at its other end to the lower portion of the pneumatic. When the parts are in the aforesaid positions, it will be understood that by depositing a coin through the slot 7, the operating lever 14, will be depressed by the wcight of the coin to the position shown by dotted lines in Fig. 'l, in which operation the rack 9, will he moved (lOWIIWHIdly the distance of one of its' teeth, thus bringing the contact spring 3 into ongagcmcnt with the plate 13, and thereby completing the electric circuit through the conductors 36, and 37, with the motor and causing the operation of the same, and through it the operation of the musical instrument. After thepiecc of music has been played, the pneumatic 27, will be deflated through the instrumentality of the tube 31, which as before stated, communicates with the power pneumatic of the instrument, in which operation it is evidentthat the we tension 22, will be raised from the position shown in Fig. 1, in which movement the bend 25, of the pawl 23, will pass over the Uni, of the teeth 10, of the rack, and raise the same the distance of the length of one ot said teeth, thus removing theplatc from out of con-tact with the spring 34, and cans ing the motor to cease its operation. is apparent that if it is desired to cause the instrument to play several tunes or pier-cs one after the other, several coins may be deposited through the slot 7, one at a time, which will cause the rack 9, to be moved downwardly the distance of the length of one of the teeth 11, for each coin deposited, and that as the pneumatic 27, Will'be deflated at the end or finish of each piece of music, the rack will be elevated the distance of the length of one tooth 10, foreach piece of music played, until the last one has'been finished, when the metal plate 13, will be thrown out of contact with the contact spring 34, as above described.

in the up" ward movement of the extension 22, on the pneumatic 27, the pawl 19, will be thrown out of engagement with the teeth 11, of the rack by means of the pivot pin d1, which connects the rod 29, to the link-30, and which pin is extended through saldlink toward the rack for the purpose of engaging said pawl.
